From Earth to the Stars: The ReThink Food Challenge Launched in Grand Style
A student challenge that ignites global innovation to transform food systems for a sustainable future.
A Challenge for Tomorrow
The ReThink Food Challenge is not just a competition—it’s a mission. With Earth’s population climbing toward 10 billion and resources dwindling, the need for transformative food systems is urgent. Add to this the dream of extending human life to other planets, and the challenge becomes an extraordinary test of ingenuity.This year, over 350 participants from 50 countries—ranging from biotech engineers to aspiring astronauts—came together to tackle this colossal task. Hosted by Wageningen University & Research, the challenge dares participants to dream beyond convention, devising systems that can thrive not only on Earth but in the extreme conditions of space.
Global Innovation in Action
The ReThink Food Challenge brought together brilliant minds from 148 universities worldwide, each participant contributing unique expertise to address the pressing need for food system transformation. Their innovative ideas are as diverse as the challenges they aim to solve, spanning sustainable farming, indoor cultivation, or alternative proteins.
Transforming Agriculture for Resilience
In the face of climate change, teams are reimagining farming systems to be more sustainable and circular. One team proposed a visionary concept of carbon-negative farms where plant waste is repurposed into bioenergy, creating a closed-loop system that not only minimizes waste but also bolsters local food security. Others are leveraging precision agriculture to optimize water use and increase crop yields in water-scarce regions, ensuring that farming adapts to an increasingly unpredictable climate.
Farming Beyond Earth
Indoor farming has taken center stage, especially with its potential to feed humans in extreme environments like Mars. Ideas range from fully autonomous modular greenhouses that use artificial intelligence to regulate light, temperature, and water, to systems that recycle human waste as nutrients for crops—solutions that are as relevant to urban centers as they are to space colonies.
Joining this challenge is a step closer to fulfilling my childhood dream of becoming an astronaut and developing innovative sustainable food systems that we can also use here on Earth.
Rethinking Protein Sources
As the demand for sustainable protein sources grows, participants are turning to innovative alternatives. One team is exploring bioreactor-grown edible fungi, which could provide astronauts with nutrient-dense food during long space missions. Other ideas include harnessing the protein power of microalgae and developing lab-grown meat, both of which offer scalable solutions for reducing the environmental impact of traditional livestock farming.
Why It Matters
These projects aren’t just theoretical. They’re designed to address real-world challenges, from combating malnutrition to reducing agriculture’s environmental footprint. This generation of changemakers is proving that bold innovation can—and must—redefine how we grow, distribute, and consume food.
The Kick-Off
An Astronaut’s WelcomeThe challenge launch was anything but ordinary. Moderator Nathalie Mangelaars took the stage in a full astronaut suit, immediately immersing the audience in the challenge’s space-driven vision. The hybrid event connected participants in Wageningen with an audience from all parts of the world.
A Time Capsule for the Future
Rector Magnificus Carolien Kroeze inspired the participants with a symbolic gesture: the unveiling of a time capsule. Contributions included personal visions for Earth, Moon, and Mars—messages of hope, sustainability, and innovation to be sealed for 50 years. Carolien shared her dream of a future where humanity thrives in harmony with the planet.
I envision an Earth free from hunger, where we live in harmony with climate change, ensuring clean water for all and thriving biodiversity. The same vision applies to the Moon and Mars, where sustainability, self-sufficiency, and circularity will be at the heart of everything we do.
Insights from the Frontlines of Innovation
Keynotes from Peter Scheer (founder of Semilla Sanitation) and Christel Paille (engineer at the European Space Agency) illuminated the possibilities of merging terrestrial and extraterrestrial food systems. Scheer shared his work on turning urine into fresh produce—a breakthrough already applied in space habitats. Meanwhile, Paille highlighted how organisms like cyanobacteria might be key for feeding astronauts during long-term space missions.
The event struck a lighter tone with a science quiz led by WUR researcher Wieger Wamelink, who revealed the surprising origins of everyday technologies—like the microwave, which was first developed for space missions.
Finally, jury members Sophie van Weede from Shift Invest and Bart van Meurs from DivisionQ officially launched the challenge. Their button press marked the beginning of the upcoming six months of hard work, creativity, and collaboration.
Powered by Partnership
The ReThink Food Challenge thrives on collaboration. Organizations like KWS Group, Bayer, GEA Group, V.O. Patents & Trademarks, Witteveen+Bos, Festo, or BO Akkerbouw provide not only funding but also expertise, mentorship, and networks. Together with Wageningen University & Research, these partners are empowering the next generation of food and space innovators.
Beyond Earth, Toward a Brighter Future
This is just the beginning. Over the coming months, participants will refine their ideas, turning concepts into tangible solutions. Whether it’s designing climate-resilient farms, crafting nutrient-dense space meals, or pioneering protein alternatives, these changemakers are proving that the future of food is as limitless as our imagination.
Stay tuned for updates as these innovators work to reshape our food systems—on Earth, in space, and beyond.
